“…In order to avoid unacceptable estimation errors within electron density valleys, in this article we propose a new estimation method that can be used to obtain the electron density profile, including estimation within valley layers. For an inhomogeneous ionized medium with a peak and a valley of the electron density profile, the relation between the phase delay of the reflection coefficient and the operating frequency is elucidated [7]. Then a new estimation method, which uses this spectral analysis and measurements of the propagation delay time, is suggested.…”

“…Then a new estimation method, which uses this spectral analysis and measurements of the propagation delay time, is suggested. For verification, numerical experiments, carried out by taking the inverse fast Fourier transform of the reflection coefficient [8], are performed, and the estimated electron density profile is compared with the model electron density.…”

The electron density profile in the ionosphere is measured by the total electron content (TEC). The presence of a ledge of ionization in the ionosphere affects the measured values. In this article, a new method of estimation of the electron density in inhomogeneous ionized media having a one‐peak profile is presented. This can be accomplished by measurement of the propagation delay time of multiple reflected pulses from the media. Numerical experiments are performed for verification. The estimated profile obtained by the new method and by numerical experiments exhibited good agreement with the true profile. © 1999 Scripta Technica, Electron Comm Jpn, 82(11): 1–7, 1999
